.fl t d ROOFING.

application filed January 7, 1915.

To all whom it may concern:

Be it known that i, RALPH L. SUAINWALD, J12, a citizen 01 the UnitedStates, and a resident of the city, county, and State of New York, haveinvented certain new and useful Improvements in Rootings, 0% which thefollowing constitutes a full, clear, and exact specification.

My invention relates to a new and improved roof construction employingprepared roofing.

The object of my invention is to provide a. roofing constructionconsistingof prepared roofing sheets laid in such a manner as to preventbuckling or wrinkling of the sheets, to obtain water tight scams, and togive the root an attractive appearance.

Heretofore it has been exceedingly diiiicult to lay the roofing so thatthe sheets would not be wrinkled or buckled by the relative movement ofthe roofing and the sheathing, produced by variations of tempe 'ature,humidity, loading or other causes. 1 overcome this difficulty byproviding an improved roof construction which consists in covering: the.roof with sheets of prepared roofing which are bent in such a manner asto form standing seams extending from the ridge to the caves of theroot, and to pro vide spaces into which the bent portions of the sheetscan expand whereby relative movement of the sheets and the sheathing maytake place without causing the sheets to buckle or wrinkle.

in the accompanying drawings illustrating n'iy invention. Figure 1 is across section of a roof construction embodying my invention. Fig. 2 is aview of a section of a prepared roofing sheet. Fig. is a view of a sheetin bent form; Figs. 4, 5 and 6 show modifications of the rootconstruction.

Similar reference characters refer to similar parts throughout theseveral views.

Referring to Figs. 1 to 3, of the drawings. in which I have shown apreferred form of my invention the reference character indicates theshathin g of the roof having battens fastened thereon in spaced relationto each other and in a direction ex tending from the ridge. to theeaves. The. battens. which may be of wood, meal or other suitablematerial, are spaced apart at a definite interval and serve as means forsupporting the standim seams.

The roof is covered with sheets of prepared roofing (3) which aresuitably bent Specification of Letters Patent.

in such a manner as to form standing 1 extending from ridge to eaves of3 and to provide spaces into which portions of the sheets can the sheetsis creased ale at and 5, as shown. paratively wide narrow latera thing"adaptc to overlap ing sheets on top fastened t ,etiier standing; seamraisee root.

-in carrying out my invention are bent so that the width 01? thereofinclru'lcc between the creased lines (4-), will be 52' than the width ofthe of battens or supports. 1 signed to be laid. and cons ca the bentsheet laid in l,;ctween thev h. or supports, a small space ((3) prev toallow for the relative movement sheet or shei'ithinnboards wnich may h.duced by changes in temperature or ot causes.

To facilitate. the proper sheets inio required form, the rooting ibending o to say, the lines t) are formed tance apart which is slightlyless tl interval between the battens and l (5) a e disposed so that thedistanc the lines (4.) and (5) will be approx equal to the depth of: thebattens.

In the modification illustrated in Pin:

n I employ sheet metal supports ('1) or 7 suitable form, tor the purposeof s 1p or in? the. standing seams and I secure the edges of the sheetstogether means of an suitable cap or fastener in Fig. 5, l have shownanother D1011 "ation in which I employ a plurality of or studs (9) forsupporting trio seams and a suitable cap or tas r-ner (10) for securingthe edges of the ben't' portions of the a iacent sheets.

A "further i'noi'lii'ication of my invention is illustrated in Fig. 5,wherein i have indicated a roof construction in which the edges of thesheets (3) are bent so as to "form self supporting standing seams havingexpansion spaces (6) provided between the bent portions of adjacentsheets, According to this modification the necessity of eniployingseparate battens or supports for supporting the seams is eliminated.

It will be apparent to those skilled in the art that various equivalentmeans may be employed for supporting the standing seams and for securingthe edges of the seams to gether Without departing from the scope orspirit of this invention.

What I claim as my invention and desire to secure by Letters Patent is:

A roof construction comprising sheets of prepared roofing, each havingits marginal portions folded toform standing seams and an intermediatetrough portion; said sheets being secured in such manner as to providespaces, adjacent to folded margin of the trough portion, toaccommodate-the expansion of the sheet by variation in the angle aifixedmy signature in the presence of two 30 subscribing Witnesses.
